Steps to reproduce - 1) Open Calc. 2) Add a few words with errors to the sheet. 3) Press F7 - spell checker dialog. 4) Hit correct or correct all to correct mistake. 5) Press Ctrl-Z. And Calc crashes. Writer and Impress don't crash though.
If it still crashes with latest build, can you get a backtrace: https://wiki.documentfoundation.org/QA/BugReport/Debug_Information
I can confirm with Version: 5.2.0.0.alpha0+ and 4.5; win7 regression, no crash in Version 4.0.0.3
